I'm currently using the Limera1n jailbreak for my Iphone 3GS (new bootrom) on 4.1 firmware. Limera1n is descent but the springboard crashes every now and then. I want to switch to the more stable Greenpois0n JB. I was wondering if I can just run the greepois0n JB as is, or should I restore my Iphone via Itunes first? Also, if I can JB over another JB, will I keep my apps, or will I have to re-download them?
Thanks!
Thanks!
